Abstract (en)

A heating device (100) for electrically heating a heat transfer fluid, comprising a housing (110) delimiting an internal volume (114) which comprises at least one chamber (150) delimited by an outer wall (159) for circulation of a heat transfer fluid, the circulation chamber (150) having at least a first internal space (151) and at least a second internal space (152) separated from each other, at least partly, by a partition (153) with a passage (156) formed so as to allow circulation of the heat transfer fluid there between, an inlet hydraulic connection member (103) connected to the first internal space (151) and an outlet hydraulic connection member (104) connected to the second internal space (152), at least one first electrical heating element (154) received in the first internal space (151) of the chamber (150) and at least one second electrical heating element (155) received in the second internal space (152), the heating device (100) being configured for mounting and operation in a horizontal position in which the first internal space (151) and the second internal space (152) are arranged substantially on the same level with respect to the ground, wherein that the outlet hydraulic connection member (104) is arranged at the substantially top portion of the second internal space (152) when the heating device (100) is in the horizontal position.
